方式。 While displaying control data such as flow rate and temperature as a trend graph on the instrumentation operator's console, which consists of a CRT and keyboard, you may want to shorten the sampling period to closely monitor data changes, or change the sampling period according to the control status. When changing the sampling period due to reasons such as selecting the sampling period, the data is displayed continuously by storing information such as the time at the time of the change and displaying the changed point on the trend graph. Trend display method when changing the sampling period.
